The first Score Baja 1000 was run on October 30-31 of 1975. It w as the final Score race of that year. The Parker 400, Baja Internacional, and Score World Championship of Off Road Racing (at Riverside Raceway), preceded the 1000. For this first Score 1000, rather than a peninsula-long race to La Paz, a large loop course was laid out starting and ending in Ensenada, of about 800 miles. The first Score race to La Paz would wait until 1979.
Score was invited to run off road racing in the state of Baja California after a very poorly organized pair of races were run by the ‘Baja Sports Committee’: The 1973 Baja Mil (1000) and 1974 Baja 500 (very few racers attended). In July 1974, Mickey Thompson and his relatively new Score organization ran a very exciting and well attended race they named the Baja Internacional (renamed years later as the Baja 500 once rights to the use were granted). Originally, the 1000 race was called the ‘Mexican 1000’ and operated by NORRA (1967-1972) with races staring in Tijuana, Ensenada, and Mexicali and all finishing in La Paz. It was commonly called the ‘Baja 1000’ from the beginning. Officially renamed Baja 1000 in 1973, when Mexico’s Baja Sports Committee took over the race (for just one year). When all Baja racing was handed over to Score in late 1974, there was insufficient time to organize a 1000 that year*. 1974 remains the only year with no 1000 race.
